Have there been any successful tip-jet helicopters? by
Jeremy Thomson
I'm not aware of any tip-jet helicopters that have made it into
production.
Please correct me if I'm wrong.
At first the idea seems a no-brainer, no torque to counter, no
gearbox, should result in a lighter & thus more efficient aircraft.
I suppose the devil is in the details.
Is the problem with...

this model?
How can I find some pictures, especially a blueprint?

Undersling and 2/rev by
Stu Fields
If an over weight pilot exceeds the recommended seat weight of his
helicopter, will this affect undersling enough to cause an increase in the
2/rev vibration??? Does increasing G forces cause an increase in 2/rev??

Pop out floats on a 206BIII by
Mike Th...
We operate floats on all our Jetrangers and our 407. For a 206BIII, I think
the weight difference compared to high skids is about 75lbs. As for an
effect on airspeed I'm not so sure because I'm on the maintenance side of
the company. Yet I figure 5-10 knots. If you want some precise numbers I...

failure.I s there any evidence for this or is it just a silly rumour?

Why do gyros use tilt head rather than swashplate by
Phillip
Would a gyro with a swashplate ( just for pitch control) fly any different
(better,worse) than using a tilt type rotor head? Just more complex?
Also, I've seen some photos of early kit helicopters that appear to have
just a tilting head (no way to auto-rotate ?). Isn't this a bit of a death
wish?...
